I wanted to add, this morning when it emptied completely out, once refilled the rear brakes still worked- the front did not function at all until the brake pedal was pumped at least 10 times or so. It had just sleeted/snowed here, so it was very obvious. After some pumping, the front started to work again.
Obviously I know the system now needs bleed as well, however, it may be some sort of symptom I am unaware of.
